CompTIA Updated N10-008 Exam Questions and Answers by khalil

Out-of-band access is a remote access method that provides a separate, independent channel for accessing network devices and systems. Out-of-band access uses a dedicated network connection or a separate communication channel, such as a dial-up or cellular connection, to provide access to network devices and systems. This allows an administrator to access the management network even if the primary network connection is unavailable or impaired. Out-of-band access is a good solution for providing a redundant link to the management network in an incident response scenario because it can be used to access the network even if the primary connection is unavailable or impaired.

• The question asks about the topology that requires the most connections when designing a network.
• A topology is the physical or logical arrangement of devices and links on a network. Different topologies have different advantages and disadvantages in terms of cost, performance, reliability, scalability, and security.
• The four topologies mentioned in the question are:
• Therefore, the answer is A, a mesh topology, as it requires the most connections when designing a network.

"Using special STP frames known as bridge protocol data units (BPDUs), switches communicate with other switches to prevent loops from happening in the first place. Configuration BPDUs establish the topology, where one switch is elected root bridge and acts as the center of the STP universe. Each switch then uses the root bridge as a reference point to maintain a loop-free topology."

A physical diagram is a type of diagram that shows the physical layout and connections of the network devices and components, such as routers, switches, cables, and connectors. A physical diagram may include specifications about the fiber connector types, such as LC, SC, FC, ST, MPO, etc., that are used to link the fiber optic cables and devices. A physical diagram can help to visualize the network topology, troubleshoot network problems, and plan network changes
